My invention lrelates tor improvements in hopper bottom load dischargingcars, and is especially related to a type of hopper car suitable' jforcommercial 'and for economic track ballasting services.

One of the objects oi my invention is to provide a 4car with a largecubic capacity in proportion to dimensions and weight for yhaulingrevenue pro-` ducing freight such as coal and for the economic andconvenient unloading 'of such freight by the consignee at destination.

A further object of the invention is to providev a car for thetransportation of and the economic placement of ballast upon the railwaytrack.

A further object of `the invention is to provide Fig. 8 is an enlargeddetail section of one end of a hoppenythis sectionnbeing taken onsubstan. tially the same line 2-2 of Fig. 5 to illustrate the relationvof the upper end flange of the ycar door withr the downwardextensionvoi the end floors and to illustrate the transverseplates whichcarry the door hingesand which provide baiiles, at the ends of thehopper doors;

-illustrated'in Fig, 10

In-the drawingsfthe lower portion'of the `car body Afis shown,-havingside sills A and center sillsy E, between which 'the longitudinallyvdisposed discharge hoppers are located. The hoppers are disposed inpairs. Each hopper has two doors F' which are 'hinged together an ahinging rod 3 which, 'as shown more clearly in Fig. 5, is disposedsubstantially above the rail Rof the track so that the inside ror centerdoors of the pair of hoppers `willdirect the discharging load to thespace between the rails and the outsidedoors will direct the dischargingload outside of `the rails. Thus,

as ,i the car ymoves along the rails, particularly whenthe car is used'for ballast material, this material can be placed either in .between oroutf side of the rails, as conditions require. The end of each hopperisp-formed by afsloping end floor `sheet B and a sloping cross hoppersheet G at the center of the car. f i p The side Walls of the hoppersare formed by the longitudinally disposed side floor sheets C and theinside sloping hopper sheets D. These hopper walls are placed as low aspossible in a car body to add as much. increasevin car capacity aspossible,and in the present car it will be noted that the hoppers arevpractically within the yheight of the center sill and insubstantially/.the same level therewith. Below Ythe hoppers arevsub-hopper portions which in effect constitute the hopper dischargeoutlets. These suiza-hoppersL are formed in Vgeneral by the doors vwhenclosed, and by Vertical extensions B and Gf, respectively, of the hopperend sheets B and the cross hopper sheets G, as shown more clearly inFigs. 2 and 8, these extensions being V-shaped and forming end Walls forthe sub-hoppers. These extension walls B and G extend downwardly intoclose proximity to the inner faces of the doors when closed. In thisform they project below the edges of upturned flanges I formed at theedges of the doors. These door flanges'l lie outside of the extensionwalls B and G', and closely adjacent thereto, so that when the doors areclosed the material in a loaded car cannot pass the ends of thesub-hoppers.

As hereinbefore mentioned, the doors F of each hopper are hinged alongtheir adjoining edges on a hinging rod 3 which extends longitudinally ofthe oar beyond the edges of the doors and has bearings 2 in transversedoor supporting andy baille plate members H. These members H, as shownmore clearly in Fig. 8, are secured by rivets 4 to theunder sides of thehopper floor sheets B and G, and extend downwardly in a vertical,transverse plane to a, point considerably below the hinge rods of thedoor and are `positioned closely adjacent the door flanges I, so thatthey s sistent with clearance for movement of these door` braces. Theplates are extended below sufcient to be cooperative with the doorflanges when the doors are in open position so as to form and walls orballles in the full open position of the doors.

In the center of the car beneath the center sills are ballast spreadingplates J which serve to deflect and spread the top of the ballast pilebetween the rails. These plates lie inthe same plane as the bailleplates H on each side thereof, and

they are joined together with the baille, plates H to form a transversestrengthening member. The baille plates H, as will be noted more clearlyin Figs. 4 and 5,` have end portions H at their upper ledges, whichoverlie the spreader plates J and are riveted or welded thereto.

The spreader plates are joined to the center sills by means of angleAmembers J which are riveted or otherwise. secured to the plates andextend up into the center sill to which they are also secured.

In addition to the baille and spreader plates, there is also providedtransverse diaphragm and bearing support plates K. These plates K aredisposed immediately adjac'entand outwardly of the baille and spreaderplates, and in substantially parallel relation therewith. They areflanged at K at their top portions and are secured by rivets orotherwise to the underfaces of the sloping hopper floor platesB and G.These transverse plates K provide rigidity and transverse strengthto-the car members-and they also serve as mounting's for carrying a partof the door operating mechanism.. The sheave wheels 5 which carry thedoor operating chains are positioned between the plates K and the bailleand spreader plates H and J-. These sheaves are rotatable on the shafts6 which have bearings 1 in the plates K and the baille and spreaderplates.- The center doors are operated in pairs from jointed handles I2.located at points adjacent either side of the car. These handles aremounted on transverse CII shafts I3 which extend from side to side ofthe car just beneath the center sills and are mounted in suitable endbearings I3' provided for that purpose. The shafts I3 carry worms I4which mesh with and drive gear wheels I5, both the worms and gear wheelsof each pair being suitably closed in a housing I5. The gear wheel ofeach set is attached to and drives the longitudinally disposed shaft I'lwhich is located centrally below the center sills of the car and whichhas a suitable bearing at one end in the casting 22 which is mounted onthe downwardly extending hanger plate L, the plate L being attached toand supported by the center sill. The other end of the shaft I'I has abearing in the housing IB which encloses the worm and gear wheel.Between the spreader plates J and the transverse plate K at the ends ofthe hopper, the shaft Il carries winding drums I8 upon which the windingchains I9 and 2D wind in opposite directions when the shaft is rotated.These chains extend over idler sheaves 5 and are connected at their endsthrough the door brace extensions 4 through the housing and guide castings 2l. Thus the rotating of the shaft Il and winding drums winds thechains upon the drums and swings the center doors to closed position,and the rotation of the shaft in the opposite direction unwinds thechains and allows the center doors to open by virtue of the weight uponthem.

The side doors are individually operated by winding drum and chainconnections. As shown more clearly in Figs. fl, 5 and 7, longitudinallyextending shafts II are disposed at the side of the car beneath thehoppers and mounted in suitable bearings therefor. These shafts carryworm and gear drive connections 9, mounted in suitable housings I andadapted to be operated by jointed handles 8. located conveniently forthe operator. These shafts are provided with winding drums I0 for thewinding chains It which extend directly to and which are attached to thedoor brace extensions 4 throughthe guide castings 2l.

I claim:
